- clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same. This invention relates to improvements in umps and valve-controlling mechanism for ire service for automobiles or other vehicles. The object of the invention is to provide an efficient and reliable rotary pump and a valve-controlling mechanism whereby it will be impossible to shut ofl the hose-lines while theengline and pump are still runmng or to 'start't e engine and pump while the hoselines are closed.

A further object is to provide means whereby when two hose-line's are supplied by the pump either one of said lines may be cut off without stopping the engine.

With the above and other objects in view theiinvention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.

In the accom anying drawings, Figure 1 is a plan view of the invention, parts being shown in section. Fig. 2 is a side view of the same. Fig. 3 is a vertical cross-sectional view Iontheline 3 3 of Fig. 1, parts of the front dash or fender-plate being broken Fig. 4 is an enlarged sectional view of the throttle-valve and its operating mechamsm for one of the u'mps. Fig. 5 is a detail longitudinal sectional view through the pump-casing, showing the construction. of the pump-piston therein; and Fig. 6 7 is a cross-sectional view of the same.

Referring more particularly to the drawings, 1 denotes the frame of an automobile or other vehicle on which the apparatus is mounted. On the frame 1 at opposite sides near the front end of thesame is mounted an engine2, which may be of any suitable t e, but which is preferably in the form Zi a Cooley rotary engine. Each of said engines is provided with a-steam-supply pipe 3 and an exhaust-pipe 4. Supported upon the frame of the vehicle and connected with each of the engines 2is a pump 5, said pumps being preferably, but not necessarily, of the rotary type and consist of a casing 6, through which the shaft of the engine projects and m whichon said shafts are mounted pistons 7. These pistons are here shownas being provided with a series of radially-disposed wings p or blades 8.

To the rear ends of thepump-casing 6 are connected water-supply pipes9, the opposite ends of which project beyond the opposite sides of the velucle and are provided with hydrant connections 10. To the opposite ends of the pump-casin 6 are connected discharge-pipes 12, each 0 said pi es being here shown as separated at their scharge ends to form two discharge passages or openings for each pipe. To each of the discharge openings or passages 0f-the discharge-pipe 12 is connected a cut oif valve 13 and a hoseline connection 14. .The stems of each of the valves 13 project upwardly and are provided with beveled gear-pinions 15, with which are adapted to be engaged gear-pinions 16 fixed on the front end of operatingshafts 17, which extend rearwardly and-are provided. on their opposite ends with handwheels 18, by means of which the valves in the discharge-pipes ofthe pump may be con- 23, formed in the valve-casing 21, as shown.

Between the upper end of the valve 22 and the shoulder formed by the reduced end of the valve-stem is arranged a coil-spring 24, the object of which is toprevent the jamming of the valve upon the seats 23 when the former is broughtto a closed position.

valve 21, arranged in one side thereof, as shown.

The stem 23 of each of the valves 22 extends upwardly through a suitable guide-bracket- 25 and is Eprovided on its u)per end with a collar 26, etween which an I the bracket 25 is arranged a coil-spring 27f The tension of 'said spring is exerted to hold the valve 22 in roo The valvecasing 21 is also provided with a relief check an open position. Pivotally connected to the upper end of the stem 23 1s a lever 28, to each end of which is pivotally connected short links 29, which are in turn pivotally connected to the lower end of vertically-disposed plungerins 30, slidably mounted in suitable guiderackets31,asshown. Above the brackets 31 are pivoted segmental wormears 32, on the lower sides of which are ormed cams 33, adapted to be engaged with the upper ends of the plunger-pins when said worm-gears are turned in the proper di-' By this construction it will be seen that when one or the other of the hose-linevalves on either side of the apparatus is closed throu 'h the shaft 17 connected therewith said shaft through its worm 34 will turn the worm-gear 32 connected therewith, causing the cam thereon toforce the plunger with which it is en aged downwardly, thus rocking the valveever 28 loosely on its pivotal connection wit-h the valve-stem 23 without moving said stem or valve, thus permitting the pump to still continue the su ply of water to the other pipe connection 0 this side of the apparatus. As soon, however, .as the opposite hose-line valve of this side of the a paratus is closed through the opposite sl faft 17 the gears connectedwiththis shaft will cause the cam thereon to force down the plunger-pin connected'with the opposite end of the valve-lever 28, which will necessarily force the valve-stem 23 downwardly against the tension of the spring 27 and close the throttle-valve, thus cutting off the supply of steam to the engine on this side of the a paratus and stopping the pump. When 0th the hose-line valves have thus been shut off and the throttle-valve closed and it should be desired to use but one pipe-line, the shaft 17 connected with the valve thereof mav be turned to open said valve, and thereby simultaneously operate the gears connected therewith, which will turn the cam on said gears in a direction to release the plunger-pin engaged therewith, thus permitting the spring 27 on the throttle-valve stem to rock the valve-lever 28 upwardly, allowing the throttle-vaive to open and supply steam to the engine, which will cause the pump connected therewith to force water through the 0 en pipe-line, as will be understood. The va ve-. operating mechanism connected with the opposite end of the lever may be turned to open the other pi e-line valve when desired, so that water w'l be supplied to both the pi e-lines on this side of the apparatus. It W1 1. be understood that the throttle-valve for the engine and pump on the opposite side of the apparatus 1s provided with similar controlling mechanism connected with the operating-shafts 17 for the pipe line valves on this side.

Arranged in rear of the throttle-valve-controlling mechanism is a vertically-dis osed fendcr-plate or dash 35, throu h whic the ends of the val ve-o )erated rafts 17 are passed, as shown. T e dash 35 being preferably provided with sliding doors 36, ar ranged on each side thereof, permits access to the throttle-valve-eontrolling mechanism in the rear of the same. The boiler 20 may be i of any suitable type and arranged on the frame of the vehicle in anysuitable manner, said boiler being shown in the drawings in dotted outline in an upright form.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention as defined by the appended claims.
